By comparing the numerical data for the response functions of the UBV color system originally given by Matthews and Sandage (1963) with the improved functions published by Ažusienis and Straižys (1969), taking into account of the extinction values given by Melbourne (1960), the response function of U and B is found corrected for a printing error and other mistakes.
